CHARLOTTE, N.C. (AP) – NASCAR placed crew chief Paul Wolfe on probation for the rest of the 2015 season after NASCAR caught Team Penske pulling out the fenders on Brad Keselowski’s car before qualifying at Las Vegas Motor Speedway.

The NASCAR penalties announced Tuesday night included a $25,000 fine on crew chief Steve Addington because Justin Allgaier’s car was too light in postrace inspection Sunday.

Wolfe’s penalty was considered a P2 penalty on NASCAR’s scale. Addington’s was a P3. The most severe is a P6.

Keselowski’s car was pulled from the qualifying grid right before Friday’s session began and sent back to inspection because NASCAR said the fenders by the wheel wells had been flared. It was a point of contention last season as NASCAR did not have a specific rule banning the flared sideskirts.

The fine against Addington was because ballast from Allgaier’s car fell out during the race. It caused the car to not meet minimum weight requirements after the race.
